I have seen that thread. Good read. The engine also has a Holley double pumper carb installed, but I have no idea if that is a factory replacement piece or an upgrade. To me, coming from 17 years behind a Rinker 180 with the 3.0 I-4 Merc, this thing is going to drink a ton of gas.

Once you get the boat and post a pic of the carb a dozen guys will ID it in a heartbeat.
More fuel than 3.0 Merc, yes . . . but a whole lot less than the massive engines in the new X's. Your boat is also so much lighter than the new beasts. That big block will hardly need to yawn!

That's a beautiful example of a 91 ProStar. It is in great shape and 500 hrs is nothing. Yes, it will use more gas than your Rinker. The faster you go...the thirstier it gets. So if you do alot of footin' you'll be at the pump alot.

One thing to consider is if the carb isn't original, it may not be a marine carb, and could be used in your favor if you haven't set a price already. A couple decent pics will get you the answer quickly enough.

I posted the only engine picture I have. Don't think it could be ID from it. Just from talking to the owner, I would guess it is the correct carb. He has had it for 12 years, and had all the right work done. Replaced the exhaust manifolds recently as well.

Can't tell enough from that pic. Need to see the carb with the flame arrestor off. The only reason I brought that up is from your earlier post that said it has a double pumper carb, and marine applications don't normally use a double pumper carb. Again, I'm not a GM guy, so don't take my word as gospel.

Everything else looks great, even the fuel pump vent line running to the carb. I only bring up the non-original parts as my '77 came with non-marine starter and carb. As this was my first inboard, I didn't know the difference, but quickly learned the ropes from all the knowledgeable folks around here.
